What is bone and what is meat in calligraphy?

The so-called bone is the frame structure of calligraphy characters (the density, distance and neatness between words), the density, stability, spatial distribution, font size, stroke spacing, opening and so on between strokes. In short, it is a combination of distance and angle. The so-called meat refers to the thickness, length, smoothness, kink and uniformity of strokes. The basic practice of calligraphy lies in the "bone" of calligraphy, and the essence of calligraphy lies in the "flesh". Calligraphy with bones and no flesh has no wonderful feeling, and calligraphy with flesh and no bones has no harmonious feeling. Therefore, beginners of calligraphy should first learn from the "bones" of calligraphy, and then practice various fonts at the advanced stage.
